Heh thoose updates are released within the last 3 days, you cant expect the creators of xampp to update the package every time one of the components are updated, plus they need time to recomplie the packages and test the new configuration.
Remember patience is a Virtue

Another thing is that non of the updates are critical, it´s only bug fixes and minor changes, so there shouldent be a reason to why you cant wait.
Or you have the possibility to update the packages your self, if you really "need" them that quick.
